Hydrogenated-Graphene-Encapsulated Graphene: A Versatile Material for Device Applications.

ABSTRACT: Graphene and its heterostructures exhibit interesting electronic properties and are explored for quantum spin Hall effect (QSHE) and magnetism-based device applications. In present work, we propose a heterostructure of graphene encapsulated by hydrogenated-graphene, which could be a promising candidate for a variety of device applications. We have carried out DFT calculations on this system to check its feasibility to be a versatile material. We found that electronic states of multilayer pristine graphene, especially the Dirac cone, an important feature to host QSHE, can be preserved by sandwiching it by fully hydrogenated graphene. The interference of electronic states of hydrogenated graphene was insignificant with those of graphene. States of graphene were also found to be stable upon a
